6.6 Changes in MySQL Connector/J 2.0.9 (2002-01-13)

Bugs Fixed

DataSource implementations moved to
org.gjt.mm.mysql.jdbc2.optional package, and
(initial) implementations of
PooledConnectionDataSource and
XADataSource are in place (thanks to Todd
Wolff for the implementation and testing of
PooledConnectionDataSource with IBM WebSphere
4).

Removed concatenation support from driver (the
|| operator), as older versions of VisualAge
seem to be the only thing that use it, and it conflicts with the
logical || operator. You will need to start
mysqld with the
--ansi flag to use the
|| operator as concatenation (bug 491680).

Full synchronization on methods modifying instance and
class-shared references, driver should be entirely thread-safe
now (please let me know if you have problems).
